    I recently bought some boraras urophthalmoides for my 45x27x30 cm aquarium and they constantly swim up against the glass. They are the smallest fish I could get and my previous boraras brigittae did this not. Now there are a few brigittae left and they also swim against the glass now.

    No ammonia levels
    Good surface ripple

    Why are they doing this it really bothers me.

    Do they appear to be trying to itch themselves or are they just swimming by the glass? If it's itching, it could be anything from ich (which I assume you'd notice, so I doubt it) to some type of metal present in the water that's irritating them.

    Could be glass surfing as they were recently added to their new environment :D
    But then again I am not entirely sure.
